Metropolis can do sex comedies. Its 2010 production of Out of Order(my review) was sidesplitting. This play, however, doesn’t even have the saving grace of being a droll period piece. It just feels dated.

Robert Danvers is a famed, 41-year-old gourmet with a voracious appetite for women. His pickup line, “My God, but you’re lovely,” became a catchphrase after the film hit theaters. As Robert’s friend and publisher Andrew Hunter puts it, “Your sex life is like a continual wine tasting: you roll ’em around and spit ’em out.” We see Robert seduce his regular bed partner, Clare, despite her determination to stop seeing him due to her impending marriage; we watch him hit on Paola, his friend’s Italian babysitter; and finally, we see him bring home Marion, an irreverent and unromantic 19-year-old.

That’s the first act: so much stage setting, which drags along. Things get somewhat livelier in the second act, commencing with arrival of Jimmy, Clare’s drummer boyfriend. But beyond the amusement factor in seeing gender tables turned, the comedy’s humor just doesn’t hold up.

The supporting cast does a fine job. Lisa Savegnago is deliciously arch as Clare,Chuck Sisson expressive as the long-suffering apartment porter, John, and Ashlee Edgemon charming as Paola. Colin Wasmund as Andrew and Sean Walsh as Jimmy are both very comic. But they aren’t enough to save the play from its moldy script.

Moreover, Russell Alan Rowe comes off as older than the part he’s playing, giving his character more chickenhawk aspect than the playwright probably intended. Shanna Brown, as Marion, goes beyond pragmatism into stolidity, and it becomes hard to see any chemistry between the two.

Not helping the continuity is the decision of Director David Belew and his designers to move the play’s setting forward into 1968. That gave Sound Designer William A. Franza greater choice of incidental music, but it doesn’t all quite fit. Playwright Terence Frisby was looking back at the early 1960s by the time his comedy opened, and the dividing line between that cocktail-soaked Mod Era and the heady hippie years succeeding it is pretty definitive: the 1967 “Summer of Love.” Cathy Tantillo’scostumes anachronistically straddle the line, with Clare in smart styles reminiscent of Courrèges and a pillbox hat and gloves, and Marion in a Mondrian-inspired minidress, but Jimmy in tie-dye and Dr. Martens.

Although there’s nothing majorly wrong with this production, with so little merit to the script, I can’t help but wonder why Metropolis didn’t turn its talents to a more worthy project.
